The Asics Women's MAGIC SPEED? 3 shoe is designed to support your racing goals. In addition to the softer cushioning experience, this shoe helps create better stability throughout your stride. ? A full-length carbon plate is sandwiched in the midsole to propel your foot forward. This helps create a smoother and more propulsive experience during the toe-off phase of your stride.? Both layers of the midsole are reconstructed with FF BLAST? PLUS cushioning. This makes the ride feel bouncier and more energetic during tempo runs and races.
